Use integers to represent the values in the statement.

Svetradugi [14.3K]

Answer:

Highest Elevation: 14240

Lowest Elevation: -285

Step-by-step explanation:

Given

$Highest\ Elevation = 14,240\ ft$ above sea level

$Lowest\ Elevation = 285\ ft$ below sea level

Required

Represent both altitudes as an integer

For the Mountain:

Take the sea level as 0 feet

$Altitude = Highest\ Elevation - Sea\ Level$

$Altitude = 14240 - 0$

$Altitude = 14240$

Hence, the integer is 14240

For the Valley:

Take the sea level as 0 feet

$Altitude = Sea\ Level - Lowest\ Elevation$

$Altitude = 0 - 285$

$Altitude = -285$

Hence, the integer is -285
